Types of Stainless Steel Sections
Beyond hollow sections, stainless steel sections and stainless profiles include a wide family of structural and architectural products.
In addition to SHS, RHS and CHS, HL Metal supports projects with a full range of stainless sections:
- Stainless steel I-beams and H-beams
- U-channels (C-channels) and special channels
- T-sections for architectural and structural details
- Equal and unequal stainless angles
- Flat bars, round bars and shafts
- Custom stainless profiles designed for specific projects
These stainless profiles are used in structures where both mechanical strength and corrosion resistance are critical – such as bridges, coastal buildings, food production facilities, chemical plants, canopies, staircases, handrails and modern glass-steel facades.
Main Stainless Steel Grades
- 304 / 304L – General purpose, indoor and mild outdoor environments
- 316 / 316L – Marine, coastal and chemically aggressive atmospheres
- 409 / 430 – Automotive and temperature-resistant applications
- Duplex grades – Higher strength and excellent chloride resistance
Based on your process conditions (humidity, salinity, temperature, chemicals), our technical team helps you select the correct grade and surface finish.
Advantages of Stainless Steel Hollow Sections & Profiles
Stainless steel hollow sections deliver a unique combination of performance, design freedom and sustainability:
- Corrosion resistance: Chromium-rich stainless steel forms a passive oxide layer that protects the surface against rust, moisture and many chemicals.
- High strength-to-weight ratio: Even at thinner wall thicknesses, SHS and RHS beams carry considerable loads while keeping overall structure weight low.
- Aesthetic appeal: Brushed, polished or satin stainless surfaces offer a clean, modern and premium appearance for visible architectural elements.
- Fire and heat resistance: Stainless steel retains its mechanical properties better than many other materials at elevated temperatures.
- Low maintenance: Thanks to corrosion resistance and durability, maintenance and repainting are kept to a minimum over the lifetime of the structure.
Stainless profiles also strongly support sustainability and green building goals:
- 100% recyclable without loss of mechanical or chemical properties
- Long service life – fewer replacements and less material waste
- Energy efficiency: Reflective stainless surfaces can reduce heat absorption and support building energy performance
- Contribution to LEED, BREEAM and similar green certification systems

Design & Selection Considerations
When you design with stainless steel hollow sections, choosing the right dimensions, grade and finish at the start of the project prevents costly modifications later. Key points to consider:
- Load and stress: Select the appropriate wall thickness and profile size for the expected static and dynamic loads. Our team can assist with preliminary sizing based on your drawings.
- Corrosion environment: For marine, coastal or chemically aggressive environments, choose 316 or duplex grades rather than 304.
- Thermal movement: In long spans and outdoor applications, allow for expansion and contraction with proper detailing and joints.
- Joining method: Plan for welding, bolting or clamping depending on site conditions and maintenance strategy.
- Surface finish: For visible architectural components, define whether you need mirror, brushed or matte finishes and the expected gloss level.
If you share your project information (drawing, 3D model, specifications), HL Metal can propose an optimum combination of stainless hollow sections, stainless sheets and fabrication services.

Stainless Steel Hollow Sections – Complete Buyer & Engineer Guide
Stainless Steel Hollow Sections (often shortened as SS Hollow Sections) deliver high corrosion resistance, clean aesthetics, and structural reliability for architectural, industrial, and hygienic environments. Whether you are specifying handrails and façades or building food-grade frames and process skids, stainless tubing in rectangular, square, and circular forms offers a robust and low-maintenance solution. On this page you will find an overview of types (RHS/SHS/CHS), typical sizing logic, how to read a weight chart, applicable standards, and commercial tips to accelerate sourcing.
Types: RHS, SHS & CHS
Stainless hollow sections are rolled and welded into three main families: Stainless Steel RHS (rectangular), Stainless Steel SHS (square), and Stainless Steel CHS (circular). In many specifications you will also see the umbrella terms Stainless Steel Tubular Sections and Stainless Steel Structural Hollow Sections to cover all shapes used as load-bearing members.
Rectangular (RHS)
Rectangular Hollow Sections Stainless Steel are favored when designers need directional stiffness—e.g., long spans for lintels, frames, and architectural trims. The broad face helps with cladding interfaces, brackets, and concealed fixings.
Square (SHS)
Square Hollow Sections Stainless Steel provide symmetric strength and clean, minimalist lines. They are common in balustrades, columns, modular racks, and hygienic processing equipment where easy cleaning and uniform looks matter.
Circular (CHS)
Circular Hollow Sections Stainless Steel combine smooth surfaces with excellent torsional behavior, making them suitable for tubular trusses, masts, furniture, bicycle racks, and public-space installations.
Sizes & Dimensions
Selecting the right member starts with loads, spans, deflection limits, and connection details. Our catalogue covers popular Stainless Steel Hollow Section Sizes across RHS/SHS/CHS families with matching wall thickness options. For engineering submittals, we share datasheets listing Stainless Steel Hollow Section Dimensions and section properties (A, Ix, Iy, Wx, Wy) to support preliminary sizing and connection design.
- RHS: e.g., 40×20, 60×40, 80×40, 120×60 with 1.5–6.0 mm wall options*
- SHS: e.g., 25×25, 40×40, 60×60, 100×100 with 1.2–6.0 mm wall options*
- CHS: e.g., Ø21.3, Ø33.7, Ø60.3, Ø114.3 with 1.5–6.0 mm wall options*
*Availability varies by grade and mill run; ask for current production windows.
How to Use the Weight Chart
A Stainless Steel Hollow Section Weight Chart lists theoretical mass per meter (kg/m) by size and wall thickness. Use it to estimate total tonnage, shipping weights, and support needs (racks, pallets, lifting plans). Actual shipment weights can differ slightly due to rolling tolerances and surface condition (pickled, polished, or brushed). We reconcile theoretical vs. loaded weights on your packing list for accurate invoicing.
| Type | Size (mm) | Wall (mm) | Theoretical Weight (kg/m) |
|---|---|---|---|
| RHS | 60×40 | 2.0 | ~4.0* |
| SHS | 50×50 | 2.5 | ~5.9* |
| CHS | Ø60.3 | 3.0 | ~4.3* |
*Illustrative only; request the project-specific chart for exact values and grades.
Standards & Material Options
Your Stainless Steel Hollow Section Standard typically specifies dimensional tolerances, mechanical properties, and permissible deviations. Common architectural and industrial grades include 1.4301/304, 1.4307/304L, 1.4404/316L for enhanced corrosion resistance, and duplex grades where high strength is needed. For exposed façades and sanitary environments, we supply brushed or polished finishes with documented roughness values (Ra).
Typical Applications (Construction & Beyond)
Stainless Steel Hollow Section for Construction is used in canopies, façades, stair stringers, balustrades, sun-breakers, and secondary framing. In food, pharma, and chemical plants, the smooth surface supports cleanability and corrosion control. Public furniture, transport hubs, and marine installations also benefit from stainless durability and appearance over lifecycle.
